Free tool · AI Proposal Checker
Does your proposal sound like ChatGPT?
Buyers have read a hundred AI proposals this quarter and they can smell the third one coming. Paste yours. We'll flag every known AI cliché, show where it sits, and rewrite the worst sentences so they sound like someone who knows the client.
Your text stays yours
It's processed in memory to build your result and then discarded, nothing is written to a database and nothing is kept once the response leaves our server. We don't train models on it, and there's no account for it to be attached to.
Don't paste documents you aren't free to share, someone else's RFP, or anything under an NDA.
How the checker works
01
Paste your text
Proposal, quote, cover email, anything a client will read. English and Polish are both detected.
02
See every tell, in place
A curated list of ~90 phrases that mark text as AI-written or template-filled, highlighted exactly where they appear, rated by severity, grouped by type.
03
Replace filler with specifics
The worst sentences get a grounded rewrite: same intent, no cliché, with [brackets] where your client's real facts belong.
AI checker FAQ
Is this an AI detector like the ones teachers use?
No, those guess probabilities and misfire constantly. This checks your text against a curated list of specific phrases that B2B buyers recognize as AI or template filler. Every flag is a real phrase at a real position; you judge it yourself.
Do these phrases actually hurt reply rates?
Yes, measurably. A 2025/26 analysis of 133,000+ freelance proposals found each AI-cliché phrase reduced reply rates by roughly 0.7 percentage points, and proposals with four or more got essentially zero replies. Buyers even run their own tests to catch AI-written pitches.
My text was flagged but I wrote it myself. Is that wrong?
Not at all, these phrases predate AI; AI just industrialized them. The problem isn't who wrote them, it's that they say nothing specific. The fix is the same either way: replace the phrase with a fact about this client.
So should I stop using AI for proposals?
No, you should stop using AI without context. Generic prompts produce generic text. When AI writes from your actual sales call, the client's own words, numbers and objections, the output is specific by construction. That's exactly how Proposals generates offers.
Is my text stored?
No. It's scanned, the result is returned, and the text is discarded.
